Ayu's lyrics meanings.. Help?

[chibi_sunny]

i guess in Step You, the first part means that the difference b/w reality and idealism is inseparable. You sometimes can't say which is which.
This has often happened to me in that sometimes, if something actually happens in my life, i feel like it has happened before, but cant replace it. yet the truth is that i only saw in my dreams. In your dreams (most of the time) or when you're daydreaming, things go the way you want them to go, which is your ideal vision. But reality doesn't go that way.
Maybe Ayu is saying her being w/ her loved one is the ideal thing, but reality doesn't allow it.
i dont really get the part "And as we cannot cut them off, they are opening up."

i'm not sure if this explains it at all though.
and it just so happens that this is my fave verse in whole song!!
